The major benefit of this machine is that it allows your optometrist to see both the back of your eye and a three dimensional image view beneath the surface of the regular retinal image. It has never been easier to find out the exact state and location of a particular eye condition.
Your optometrist can review the images on a PC screen and pinpoint areas of concern by digitally peeling the layers back until they define what it is that they have identified as requiring further investigation.
There may be an additional charge for the OCT scan, but the benefits are obvious. The software can automatically detect even the most subtle changes in the retina with every eye test you take. This gives an invaluable ongoing record of the health and condition of your eyes.
